Toall 'whom it may concern.-

Be it known that I, HENRY CRUSE, a subject of Great Britain, residin at `16 and .18 anchester, in the county of Lancaster, England, have in vented new and useful Improvements in the Construction of Valve-Caslngs, of whichthe following is a specification. f

My invention relates to improvements in the construction of valve casings chiefly a plicable for the type of valves common y termed full way valves.

In the accompanying sheet of drawings- Figure 1 is a sectional elevation of a full way valve and its casing, the latter made in accordance with my improvements. Fig. 2 is a sectional elevation of the same taken on the plane of the line a-b, Fig. 1. Figs. 3, 4, 5 andl 6 are sectional views of different' ways of making the joint between the two wrought metal dishes and the valve guide and are supposed to be taken on the plane ofthe line c-d, Fig. 2.4

In carrying my improvements into effect I form the valve casing of two pressed, stamped or wrought' dishes 1, 2, of wrou ht iron ory steel. These parts 1 and 2 are anged' and are united by bolts or rivets 3 passing through the anges of the dishes 1, 2, as well as through an intermediate calking ring 4,

The calking ring 4 extends far enough into the interior of the casing to act as a 1guide for the valve bridle 5 which is fitted to slide to and fro therein. The valve bridle 5 has two valve disks 6 fitted in it and these have their seatings' on the ends of two iiangedV pi e pieces or sockets '7 riveted or welded into t 1e mouths of the parts and 2. The valve bridle 5 has also a stop piece 8 and two guide forks 9 formed upon it and the, latter embrace the projecting portion ofthe calking Fig. 4,-the flanges of the cal ring 4. 'A spindle or rod v10 is secured to the .valve bridle 5 in order to operate the valve.

, The calkin ring 4 might be of T section,

as shown in igs. 3 and 4, and the dishes 1 and 2 in that case need not be flanged but would be united by bolts or rivets 11 passing ,through the Ilan es of the calking ring 4 and the ed es ofthe ishes. v

In ig. y3 the edges of the dishes 1, 2, abut and the lianged calking ring 4 is laced entirelyinside the valve casmnw ereas, in

g ring 4 lie outside the valve caslng and the shank or straight ortion at right angles to thel flanges divides t e two edges of the dishes 1, 2, and projects between them into the interior of the valve casing. Again, in Fig. 5 the calk-- ing ring 4 is flanged and secured as in Fig. 3 with this addition that a butt stra 12r is placed outside over the joint and the olts or rivets 1 1 pass through it and the flanges.

In Fig. -6 the ends of the dishes 1 and 2 overlap and the edge of the inner one is beveled ofi and then the flangedfcalking ring 4 is laid upon the joint and secured thereon by the bolts or rivets 11. ,j

What I claim :and desire to secure by Letters Fatent of the United States is A valve casing comprising two wrought metal dish shapedl members, a calking rmg extending from the junction of said members into the casing, and a slide valve in the casin the. calking ring `forming a guide for the va ve.

In testimony whereof have signed my n arne to this specification in the presence of two subscribing witnesses.

.HENRY cRUsE.
